Answer:
B. Negative
Step-by-step explanation:
Line is going downwards
Well we set the perimeter to 120 feet.
This means that 2x+2y=120
Now we know the area of a rectangle is xy so we have to solve for both x and y in the perimeter equation.
2x=120-2y
x=60-y
2y=120-2x
y=60-x
Now we plug these values into our area equation A=xy to get:
A=(60-y)(60-x)
Answer:
Would it be 5?
Step-by-step explanation:
3/2 = x/30........3 dogs to 2 cats = x dogs to 30 cats
cross multiply
(2)(x) = (3)(30)
2x = 90
x = 90/2
x = 45 dogs <===
